The effect of acetylsalicylic acid (ASA) and its complex compounds with the metals lithium (Li+), potassium (K+), magnesium (Mg2+) and calcium (Ca2+) with a single intraperitoneal injection at doses of 5, 10 and 20 mg/kg on cardiovascular system (CVS) of rats (blood pressure, heart rate, indicators of heart electrocardiogram). The structure-effect analysis showed that the coordination compounds of ASA, in which, in addition to the ligand with bioactive properties, a metal-microelement is present, caused multidirectional changes in the CVS indices. Those changes depended both on the metal included in the compound and on the dose of the administered substance. The study was carried out on the basis of the Center for collective use of scientific equipment «Experimental Physiology and Biophysics» (Department of Human and Animal Physiology and Biophysics, V.I. Vernadsky Crimean Federal University). The research of the biological effect of the acetylsalicylic acid, SLi+, SK+, SMg2+, SCa2+ was carried out during their intraperitoneal injection into rats in doses of 5, 10 and 20 mg/kg. Simultaneously the following characteristics of all the groups’ animals were registered: heart rate (HR), systolic blood pressure (SBP) and diastolic blood pressure (DBP) and electrocardiogram indicators. The pulse pressure (PP) was calculated on the basis of the SBP and DBP indices difference. BP, HR and RR of the rats were registered with the help of the system NIBP200A («Biopac Systems, Inc.», USA). The experimental data obtained in our studies confirm the literature data, which show that in the process of complexation there is not only an increase or decrease in certain effects that are characteristic of precursor molecules-salicylates, but also the appearance of new properties of derived substances. Тhe obtained data confirm the cardiotropic effectiveness of new coordination compounds, show the dose dependence of these effects and open up the prospects for further studies of their biological action when used repeatedly in chronic experiments.

In a group of healthy men of different ages (18–75 years old), the level of autophagy marker – Beclin-1 in the initial state and after a course (on the 12th day) of limited (800–1200 kcal) calorie restriction (CR) was studied by the enzyme immunodetection. Body composition was determined using impedansometry. The degree of autophagy activation was assessed by the «delta» value – the difference between the initial concentration and after CR. Normally, men showed significant variability in the level of Beclin-1 from 6.14 to 844.78 pg / ml. As a result of the CR course, there was a significant decrease in body weight, soft lean, fat and muscle mass (p<0.0001), as well as intracellular water (p<0.006). As a result of the course of CR in the entire group, an increase of 2.0 times (p<0.01) in the concentration of Beclin-1 was noted. At the same time, positive correlations were revealed in the entire study group between weight, body mass index (r = 0.46 and r = 0.48, respectively, p<0.05), fat mass (r = 0.62; p<0,01). The same patterns were observed in middle-aged people. A direct correlation was found in obese individuals between the level of Beclin-1 and the content of fat mass. In the group of young people, positive correlations between the Beclin-1 delta and the delta of individual body composition indicators were revealed: muscle (r = 0.96; p<0.05), soft lean (r = 0.96; p<0.05) weight and total water (r = 0.96; p<0.05). The loss of these body components was accompanied by a parallel decrease in the activity of Beclin-1. In old age, fat loss occurred in parallel with an increase in Beclin-1 activity (r = -0.87; p<0.05), directly correlated with HDL (r = 0.94; p<0.01) and inversely correlated with LDL (r = -0.99; p<0.01) and total cholesterol (r = -0.98; p<0.01). In young people, the opposite pattern was observed. Each age group had its own characteristics in the ratios of the studied parameters.

Currently, the depletion of the gene pool of forest woody plants is observed due to the fact that in the course of selective felling, specimens valuable for economic characteristics were destroyed and seeds from the remaining specimens were used, which did not have the best qualities. It was noted that a high level of genetic heterogeneity allows the population to adapt to changing environmental conditions, ensures the stability of the population and is a resource for breeding. The selection of valuable genotypes in the creation of forest seed plantations, which is carried out according to the phenotype, is based on the heterogeneity of populations. Meanwhile, studies show that phenotypically normal trees do not always produce good offspring. The cytogenetic method allows assessing the offspring. With its help, it is possible to distinguish among the seed offspring the mother trees of the group with different levels of stability of the genetic material. The aim of the work was to identify markers among cytogenetic parameters for the selection of trees producing seed offspring with different stability of the genetic material. The objects of the study were seedlings of seeds of phenotypically normal Scots pine trees growing in the Khopersky State Nature Reserve (51°10’56.9″N 41°44’17.2″E), and white spruce growing in the Botanical Garden. prof. B.M. Kozo-Polyansky Voronezh State University (51°42’41.57 «N 39°12’17.57″E). The trees had no visible pest damage. The method of preparation and analysis of preparations of seed sprouts is described in the work of Butorina A.K. (2000). In the course of the study, 20 cytogenetic parameters were determined: the mitotic index (counted with and without taking into account cells at the prophase of mitosis), the level of mitotic pathologies (counted with and without taking into account cells at the prophase of mitotic), the proportions of cells at the stages of prophase, metaphase, anaphase , the proportions of cells with 1–10 nucleoli in the nucleus of interphase cells, the proportion of cells with micronuclei, the proportion of cells with residual nucleoli in interphase and mitosis. Statistical processing of the study results was carried out using the STADIA 7.0 and MedCalc 17.5.3 software. The diagnostic value of the indicator is characterized by the area under the ROC-curve: 0.9–1.0 – excellent; 0.8–0.9 – very good; 0.7–0.8 – good, 0.6–0.7 – average, 0.6 and less – unsatisfactory. Among the cytogenetic indicators, there are those that are suitable for separating the mutable group from the weakly mutable and intermediate, as well as the weakly mutable from the intermediate. In pine, these include the proportion of cells at the prophase stage and the average number of nucleoli in the nucleus, in spruce – the mitotic index without taking into account cells at the prophase stage, the level of mitotic pathologies with and without taking into account cells at the prophase stage and the proportion of cells at the me

The article provides a rationale for the synthesis of environmentally friendly water-soluble polymers based on N-vinyl amide, used in various technological processes. The relevance of the work is associated with solving environmental problems of creating biodegradable materials and minimizing the negative impact of polymer materials on the environment. The aim of the work was to synthesize and characterize polymers based on N-vinylamide. The conditions for the synthesis of poly-N-vinylpyrrolidone, poly-N-vinylcaprolactam, poly-N-vinylformamide and polyacrylamide, including the temperature and time of synthesis, have been developed. Alcohols of various structures, hexane and distilled water were used as solvents; thermal initiation was carried out using dinitrile azo-bis-isobutyric acid. The viscosity average molecular weight and intrinsic viscosity of the obtained polymers were calculated. Polymers with molecular weights from 10,000 to 94,000 were obtained by radical polymerization. Polymers of the poly-N-vinylamide series are characterized by the presence of a hydration shell consisting of several layers. The structure of the hydration shell of poly-N-vinylcaprolactam, in which water molecules form hydrogen bonds with the carbonyl group of the polymer, is presented. To characterize the polymers, the IR spectra of their aqueous solutions were obtained, and the assignment of absorption bands in the obtained spectra was given. The synthesized polymers have good complexing ability, which expands the possibilities of their application for the extraction of inorganic and organic substances.

Along the federal roads of the Rostov region, Krasnodar Territory and the Stavropol Territory, it is increasingly possible to find clean plantations consisting of one or two tree species, with a completely destroyed bush belt. In 62 % of the plots studied, the shrub belt is represented by species of scumpia (Cotinus coggygria, 17 %), terna (Prunus spinosa, 9 %), elm (Ulmus parvifolia, 5 %), maple (Acer tataricum, 3 %), that is, resistant to anthropogenic and climatic factors steppe The bush belt in protective roadside strips plays a significant role in the accumulation of soil moisture (by 6.3 %), humus (by 2.4 %), in reducing the noise load (by 25 dB). Ancestral and overband shrubs make it possible to create a dense structure of forest strips, which fully performs protective functions both from drifts of the highway bed with snow, and to reduce the negative impact of vehicles on adjacent landscapes. The study of the phytomeliorative role of the shrub belt in existing roadside plantations is a relevant area of research for the further development of recommendations for the creation and maintenance of protective roadside plantings in the steppe zone of southern Russia.

The objective of the research was to study the forest conditions and forest inventory characteristics of P. pallasiana in the eastern part of the southern slope of the Main ridge of the Crimean Mountains, the evaluation of its growth in connection with high-rise zoning and dynamics of soil properties. The studies were carried out using the methods of laying hypsometric profiles. Soil characteristics were studied in soil sections in five layers with an interval of 10 cm. The ecotopic grid of the Mountainous Crimea was used for the typological classification of phytocenoses. The features of the territorial distribution of artificial coniferous stands in the study area were analyzed using the data of space sensing of Landsat 8 satellite system. As a result of the conducted studies, it was found that the forest crops of P. pallasiana in the eastern part of the southern macroslope of the Main Ridge of the Crimean Mountains in the lower belt are characterized by low taxation indicators. With an increase in the height of the growing area, their state and growth intensity improve. Dynamics of forests conditions in the study area is associated with increasing dryness of the climate, a decrease in precipitation, the number of which decreases in the direction from the central to the eastern part of the southern slopes of the Main ridge of the Crimean Mountains. The high-altitude zoning of soil fertility is revealed. In the ecotopes of the middle belt, there is a decrease in the content of humus in the upper layer of the soil, which is associated with increased erosion processes in the territory of anthropogenic degradation of forest vegetation. High seasonal variability and instability of precipitation over the years, especially in the summer growing season, the weather conditions of which largely determine the implementation of growth and development processes, reduce the stability of the structure and composition of plant communities, form a negative ecological background, which determines the deterioration of the life state of P. pallasiana forest cultures. In the research area edaphic characteristics of forest crop ecotopes of P. pallasiana in the lower and middle belt correspond to forest-growing conditions such as dry sudubrava, and in the upper belt – fresh sudubrava.

Information about the bird fauna of the reserve and adjacent territories, including their numbers, areas of permanent or temporary habitat, biotopic distribution, seasonal residence, and behavior is of interest in determining and clarifying the current conservation status of these species in a particular region. To do this, it is necessary to conduct faunal research, monitor species in General and compile (clarify) lists of bird species, in particular species of reserves and adjacent territories. State Naturе Reserve «Opukskiy» (further − the reserve) is a protected area that ensures the protection of unique natural complexes of the South of the Kerch Peninsula on the narrow coastal strip from Western tip of Kojashskoe lake to Chebakskaya beams (near Yakovenkovo). The location of the reserve determines its significance for the conservation of bird species that nest, migrate along the black sea coast and winter in the protected water area. The reserve plays an important role in maintaining breeding populations of rare and protected species of birds and are most numerous in the South of the Kerch Peninsula winter waterfowl, a transit district of rest and feeding for migratory birds and breeding areas of some species. Numbers in the last published list of bird fauna of the reserve [13] reflect the reliability of the presence of the species in the described territory. Baseline – 195 bird species in the reserve; 205 – taking into account adjacent areas [13] only in the reserve and adjacent areas was 241 and 263 species of birds, respectively, 46 and 58 species more above baseline. In this article, the author presents additions that provide information about the registration of new species of bird fauna in the reserve and adjacent territories and their status listed in the list. It contains information about 68 species of birds, 39 of which were registered in the reserve for the first time, 17 species of birds were found in neighboring territories, and 7 species were confirmed to be present in the reserve [13]. The State Nature Reserve «Opukskiy» plays an important role in maintaining breeding populations of rare and protected species of birds and are most numerous in the South of the Kerch Peninsula winter waterfowl, a transit district of rest and feeding for migratory birds and breeding areas of some species. Additions to the list of avifauna of the reserve and adjacent territories provide information on the species composition and state of the bird fauna, their current status and seasonal residence periods for the period from 1989 to 2020. 241 species of birds belonging to 132 genera, 53 families and 20 orders were registered on the territory of the reserve between 2011 and 2020, of which only 97 (39 %) nest relatively regularly. Among them – 39 new species for the reserve, and for 22 species – confirmed presence in neighboring territories. The total list of avifauna of the reserve and adjacent territories is 263 species of birds, which is 78 % of t

Currently, the problem of improving the quality of the training process in both professional and novice athletes is a priority for experts in the medical and biological support of sports all over the world. For these purposes, various biofeedback procedures, including the method of solving specialized motor-cognitive tasks on the stabilometric platform [1], have been actively used in recent years as extra-training means to improve sports performance. At the same time, we should note that one of the most informative biological signals that allow to judge about the change in the functional state of the body of the tested athletes in the process of sports training is the dynamics of heart rate variability (HRV) [2]. HRV analysis is widely used as a non-invasive and reliable tool for assessment of vegetative control of human cardiovascular system [3]. Numerous literature sources confirm the prospect of using this method for the purposes of sports physiology [4] However, changes in HRV in highly qualified athletes when solving complex motor and cognitive tasks, as of today, still remain unstudied. The aim of the present study was to assess changes in heart rate variability in highly qualified orienteering athletes when solving complex coordination tasks on biocontrol of a virtual object using a stabilometric platform ST-150. Seven days training with biofeedback control on the stabilometric platform resulted in a significant increase of such HRV temporal indices as SDNN – by 8,9 % (p<0,01), RMSSD – by 42,3 % (p<0,05), pNN50 – by 77, 1 % (p<0.05), CV – by 25.3 % (p<0.01), as well as heart rate reduction by 10.5 % (p<0.05), which indicates an increase in functional capabilities of the athletes’ bodies, strengthening vagus effects on cardiac rhythm. The results of geometrical analysis have shown that biofeedback according to reference reaction leads to reliable increase of values of index of mode of cardiointervals by 9,7 % and increase of variation range of histogram of cardiointervals by 21,4 % as well as decrease of values of mode amplitude by 19,2 % and tension index of regulatory systems of the body by 29,6 % (p<0,05), which testifies to improvement of adaptation possibilities of the body of tested sportsmen under the influence of this type of biocontrol. Analysis of spectral components of heart rhythm in orientation athletes after 7-day training with biofeedback control has shown significant increase in TP by 36 %, LF – by 37,7 %, HF – by 88,2 % as well as decrease in LF/HF by 28,2 % (p<0,05), which testify to increase in general variability of heart rhythm, activation of parasympathetic regulation circuit, increase in functional capabilities and reserves of tested athletes organism.

The study is devoted to ontomorphogenesis and the structure of cоenopopulations of the rare species Crepis purpurea (Willd.) M. Bieb., protected by the Red Data Book of Sevastopol, the Republic of Crimea, Turkey and I Appendix of the Berne Convention. The duration, morphological and anatomical features of the age states in the pregenerative, generative and senile periods of C. purpurea ontogenesis are established. The total duration of ontogenesis is 5–6 years, which includes 4 ontogenetic periods and 9 age states. C. purpurea is characterized by the structural type of polyvariance with the formation of 3 ontobiomorphic variants: individuals with one-, two-, or many-headed caudex. The features and the period of the onset of anatomical partition in the shoot part caudex were revealed. Germination of C. purpurea seeds was determined. The ontogenetic, vitality and spatial structure of 11 Crimean cоenopopulations of C. purpurea were carried out. The lack of the pregenerative and senile individuals fractions is observed in coenopopulations. The basic ontogenetic spectrum of the studied populations is bimodal with a peak on virgin and mature generative individuals. The indices of renewability, generativeness, aging, the general age of the population, as well as the age indices of A. A. Uranov and the efficiency of L. A. Zhivotovsky were calculated for each population. In the vital structures there is a dynamic on the increase in the values of the index of vital quality of populations from the eastern foothills to the western foothills and further – to the mountain plateaus variants of populations. It was established that individuals of C. purpurea have a tendency to tend to a group type of distribution in the population. The data on areas of coenopopulations, the number and density of individuals of C. purpurea in the studied communities are presented.

In the Primorsky Territory, the economic use of introduced species of conifers is poorly developed. Local species are traditionally preferred in forestry and gardening. The objects for the cultivation of introduced coniferous species can be recreational forests, forest park zones and areas of landscaping of settlements. This will increase the biodiversity of existing natural and artificial plantations and enhance their aesthetic appeal. The aim of the research is to summarize the material on the results of the introduction of European pine species in the arboretum of the Mountain Taiga Station. The rhythm of seasonal development of Pinus mugo Turra, p. hamata D. Sosn., p. pallasiana Lamb. The local species -p was taken as a control. koraiensis Siebold et Zucc. The main climatic indicators of natural areas of pine trees are analyzed. The similarities and differences of these indicators with the climate of Primorsky Krai were revealed. Natural ranges of Pinus mugo, p. hamata., p. pallasiana. characterized by a warmer climate compared to the Primorsky Territory. Theoretically, there may be a danger of freezing of buds and shoots in these species in years with a high value of negative temperatures. However, during the observation period, we did not notice signs of freezing of buds or shoots. All three pine species, when introduced to the Primorsky Territory, may experience tension in seasonal development due to insufficient heat. This is reflected in the lengthening of the growing season in comparison with local coniferous species. All species in the arboretum have reached reproductive age and are in good health. Biometric parameters of pine species under conditions of introduction generally correspond to similar sizes in their natural range. The exception is narrower needles at the place of introduction near the river. mugo. The length and width of the cones of the three pine species in the arboretum are within the indicated sizes in their natural habitat. Moreover, the average length of the cones p. pallasiana under conditions of introduction is at the lower limit of fluctuations in this parameter at home. The width of the cones r. mugo – at the upper border. The rhythm of seasonal development of introduced pines corresponds to the annual dynamics of the climate in the conditions of Primorsky Krai. Calendar dates of phenological phenomena are close to the local species p. koraiensis Siebold et Zucc. All plants complete the growing season at favorable times relative to the period with stable frosts. The relationship between the duration of shoot growth and the size of their annual growth is not traced. The lowest growth rate is characterized by p. mugo, greatest p. koraiensis. Pinus mugo, p. hamata., p. pallasiana can be recommended for increasing the biodiversity of recreational forests, forest parks and green areas in settlements.
在滨海边疆区，引进的针叶树的经济利用还不发达。传统上，林业和园艺更喜欢本地物种。引种针叶林的栽培对象可以是游憩林、森林公园区和聚落景观区。这将增加现有自然和人工种植园的生物多样性，并提高它们的美学吸引力。摘要本研究的目的是总结在针叶林站植物园引进欧洲松种的结果资料。松木季节发育的节律，p. hamata D.
